Description
本新型是有關於一種連接裝置,特別是指一種用於連接管件的連接裝置。 The new model relates to a connecting device, in particular to a connecting device for connecting pipe fittings.
玻璃纖維強化塑膠(FRP,Fiber-reinforced plastic)管件是以樹脂及玻璃纖維為原料,並經交叉纏繞工藝所製成,具有管壁結構強度高及耐腐蝕等優點。當要連接不同的管件時,會需要透過連接裝置來接合這些管件,由於這些管件會遇到熱漲冷縮、管路拉扯、強勁的水壓等使用情形,因此管件之間常會在徑向及軸向上受力,另外,當管件受到太陽曝曬或環境低溫而產生熱漲冷縮之情形時,管件之間會伸縮變形,通常會利用連接裝置,連接兩側管件,吸收管件間因熱脹冷縮而產生的變形量,並達成緊密連接管件而不致洩漏之功效。 Fiber-reinforced plastic (FRP, Fiber-reinforced plastic) pipe fittings are made of resin and glass fiber as raw materials, and are made by cross-winding process, which has the advantages of high structural strength and corrosion resistance of the pipe wall. When connecting different pipe fittings, it is necessary to join these pipe fittings through a connecting device. Since these pipe fittings will encounter thermal expansion and cold contraction, pipeline pulling, strong water pressure, etc., the pipe fittings are often radially and In addition, when the pipe fittings are exposed to the sun or the environment is low temperature and cause thermal expansion and cold contraction, the pipe fittings will expand and contract. Usually, a connecting device is used to connect the two side pipe fittings to absorb the thermal expansion and cooling between the pipe fittings. It reduces the amount of deformation caused by shrinkage, and achieves the effect of tightly connecting the pipe fittings without leakage.
從上可知,該連接裝置應具備高強度、耐腐蝕,且能有效吸收兩管件間伸縮變形量之功效,現行做法是設置一與該等管件相同材質且兩端分別連接該等管件之U型連接件,藉由U型連接件兩 側分別與該等管件同軸之特性,即使該等管件分別軸向伸縮,該U型連接件將會隨之移動而不會造成破損,確實能有效吸收兩管件間之伸縮變形量。然而,該U型連接件無法沿一相同的軸線連接該等管件,設置所需之空間大,而需另外的中間支撐結構維持,且自身不具有承受高頻振動的能力,當該等管件設置於幫浦附近時,該等U型連接件將可能因為高頻振動而破損,因此這種連接方式尚有很大的改善空間。 From the above, it can be seen that the connecting device should have high strength, corrosion resistance, and can effectively absorb the expansion and contraction between the two pipe fittings. The current practice is to set up a U-shape of the same material as the pipe fittings and connecting the pipe fittings at both ends. connector, by means of two U-shaped connectors Since the two sides are coaxial with the pipe fittings, even if the pipe fittings expand and contract axially, the U-shaped connecting piece will move along with it without causing damage, which can indeed effectively absorb the expansion and contraction between the two pipe fittings. However, the U-shaped connector cannot connect the pipes along the same axis, the space required for installation is large, and another intermediate support structure is required to maintain, and it does not have the ability to withstand high-frequency vibration. When the pipes are installed When near the pump, these U-shaped connectors may be damaged due to high-frequency vibration, so there is still much room for improvement in this connection method.
因此,本新型之目的,即在提供一種能吸收位移振動、耐用度高且使用壽命較長的連接裝置。 Therefore, the purpose of the present invention is to provide a connecting device capable of absorbing displacement vibration, high durability and long service life.
於是,本新型連接裝置包含二沿一軸線方向彼此相間隔地同軸設置的承接件、一以金屬材質製成並沿該軸線方向設置於該等承接件之間的波紋管、二沿該軸線方向分別固定於該等承接件外側的適配法蘭,及複數沿該等適配法蘭的周向彼此相間隔地呈環狀排列的拉桿。該波紋管包括複數彼此相互連接而可沿該軸線方向伸縮的彎折段,及二由最外側的兩個彎折段朝外延伸以分別接抵該等承接件的延伸段。每一拉桿沿該軸線方向延伸,且兩端分別固定於該等適配法蘭上。 Therefore, the novel connecting device comprises two coaxially spaced coaxially disposed receiving members along an axis, a corrugated tube made of metal material and disposed between the receiving members along the axis, two bellows along the axis The adapter flanges are respectively fixed on the outer sides of the receiving parts, and a plurality of tie rods are arranged annularly at intervals along the circumferential direction of the adapter flanges. The bellows includes a plurality of bending sections which are connected to each other and can expand and contract along the axis direction, and two extension sections extending outward from the two outermost bending sections to contact the receiving parts respectively. Each pull rod extends along the axis direction, and two ends are respectively fixed on the adapter flanges.
本新型之功效在於:該波紋管可沿該軸線方向伸縮,從而可吸收該等管件在該軸線方向上的變形量,且能夠同軸連接該等 管件,大幅減少設置所需之空間,而不需另外的支撐結構維持,且具有承受高頻振動的能力,加上該波紋管以金屬製成,具有耐腐蝕、耐高溫及耐壓之優點,因此可提高耐用度及使用壽命。不僅如此,以金屬製成的該波紋管也有較佳的強度,而能克服習知之問題。 The effect of the new model is that the corrugated pipe can expand and contract along the axis direction, so as to absorb the deformation of the pipe fittings in the axis direction, and can connect the pipes coaxially. The pipe fittings greatly reduce the space required for installation, without the need for additional support structures to maintain, and have the ability to withstand high-frequency vibration. In addition, the bellows is made of metal, which has the advantages of corrosion resistance, high temperature resistance and pressure resistance. Therefore, durability and service life can be improved. Not only that, the corrugated tube made of metal also has better strength, which can overcome the conventional problems.
